GSM IG V

08 (

GB

)

The battery-12V supply from the Memcom is available using the power breakout cable provided. The +12V core 
is sleeved red, the 0V core is sleeved black. This is then connected to the travelling cables to take the power supply to 
the GSM terminal. The maximum resistance for each core is 1ohm. Use more cores in parallel if it is a very long run and the 
resistance is higher than 1ohm.

Note: If a battery-12V power supply is available at the GSM installation point then this may be used instead, 
a current of 0.5A peak would be required. Note that unless this supply is monitored then the system may not be EN81 
compliant.

The Memcom PSTN connections are wired so Pin 1 of the 1st Memcom is connected to Pin 1 of the next Memcom and so 
on. Pin 1 of any Memcom is connected to the GSM “TIP” on the terminal block.

Similarly, all the Memcom Pin 2 connections are wired together and then to the GSM “RING” input. Do not swap over any 
connections as problems with the Memcom and the GSM will occur.
